No I don't think all Christians speak in tongues. There are many gifts.
Scripture is God's final word on doctrine. Though in every day life, the Holy Spirit can give insight and
wisdom on day to day things. Like for example in 2015 my aunt wasn't herself. It wasn't something
I could pin point, but I just felt this absolute panic and urgent need to call an ambulance.
The paramedic responder came and asked what was wrong, I said I don't know she just
needs help. He looked at me as if I was stupid, as my aunt didn't look that ill.
Anyway he checked her vital signs and found her blood pressure was in her boots and her
heart was racing. Then in the next breathe he asked for an urgent ambulance with blue lights.
It turned out she had heart failure, her kidneys were failing, her lungs were filling up.
But she honestly didn't look that bad! I believe that was the prompting of the holy
spirit, if I hadn't listened she would have been dead. I could give many examples of
the prompting of the Holy Spirit.
I think the Holy Spirit does give instructions and insight, rather than new revelations.
He is teacher councillor guide etc. He opens up the scripture to us. He makes the penny
drop!
Slain in the spirit, it depends what you mean by that. On rare occasions I've seen
people fall under the power of God during Genuine encounters. One was during an engagement
party, we were praying with the bride and groom to be, suddenly in perfect synchrony,
they both fell backward. Well actually it wasn't even like a fall, they were literally
pushed off their feet! It was entirely different to the sudden wobble general falling over you
see on TV, they were also both completely unharmed.
Im sceptical though about what many refer to slain in the spirit and drunk in the spirit as
it can also be hysteria or people mimicking each other. The real deal though is definately
God. It's different to the "swooning" you see on TV programmes. I also don't like it when
pastors and speakers try to get a crowd hyped up. That's man made hype.
Ive experienced the power of the Holy Spirit several times but I've never fallen over.
But in my experience, people fall silent under the power of the Holy Spirit.
Now that I have experienced, an entire congregating of 1000 people just go completely
silent apart from sobbing here and there as the waves of His presence flood the church.
